The show tries to look into the ancient rituals of Stonehenge - including possible human sacrifice - and whether the circle was a temple of the dead. They bang some drums and find the stones echo the drumbeats back. They speculate that the ritual sounds of Stonehenge may have had a hypnotic effect on those in the ceremony -- an effect contributed to by torches, which may have pulsed in time with the drumbeats, too (because of the sonics). They also speculate that a body found with arrowheads may have been executed by ritual firing squad - though there is little other evidence of this. In the end, this was an interesting experiment, but little more.
